Causes Of A Nosebleed
Most nosebleeds (epistaxis) are mere nuisances. But some are quite frightening, and a few are even life threatening. Physicians classify nosebleeds into two different types.

Posterior nosebleed: More rarely, a nosebleed can begin high and deep within the nose and flow down the back of the mouth and throat even if the patient is sitting or standing.

Additional Causes Of Nosebleeds:
Allergies, infections, or dryness that cause itching and lead to picking of the nose.
Vigorous nose blowing that ruptures superficial blood vessels in the elderly and in the young.
Clotting disorders that run in families or are due to medications.
Fractures of the nose or of the base of the skull that can cause bleeding and should be regarded seriously when the bleeding follows a head injury.
Rarely, tumors (both malignant and nonmalignant) have to be considered, particularly in the older patient or in smokers.
Treatment For Nosebleeds
Many physicians suggest any of the following lubricating creams or ointments. They can all be purchased without a prescription: Bacitracin, A and D Ointment, Eucerin, Polysporin, and Vaseline. Up to three applications a day may be needed, but usually every night at bedtime is enough. A saline nasal spray will also moisten dry nasal membranes.

If the nosebleeds persist, you should see your doctor. Using an endoscope, a tube with a light for seeing inside the nose, your physician may find a problem within the nose that can be fixed. He or she may recommend cauterization (sealing) of the blood vessel that is causing the trouble.

A piercing maybe... ummm... I could go on....

commonest cause is a deviated nasal septum ( center part of the inside of the nose) in the presence of dry air , the flow of air cuses dryness in that septum mucosa ( the lining of the nose) which when dry it would crack and start bleeding
other less comon cuases are high blood pressure, drugs , and rare condition such as bleeding tendencies ( hemophelia etc)
